Stowaways should get a PDA.

Give 'em an emergency o2 tank. Maybe even less full than normal ones and potentially already equipped (if possible).

Reason being your spaceguy took at least some precautions to survive the trip, since at least part of it might've involved depressurized environments.

this seems like a fair compromise. O2 is essentially ridiculously easy to get, anyways.
